WATER-PUEIFYING APPARATUS.

Application filed April 15, 1:913.

T 0 all whom it may concern:

Be it known that 1, WILLIAM J. Cnow, a citizen of the United States,residing in Independence, in the county of Jackson and State ofMissouri, have invented a new and useful l Vater-Purifying Apparatus, ofwhich the following is a specification.

My invention relates to improvements in water purifying apparatus forsteam boilers in which the impurities are separated from the waterthrough the agency of heat and gravity; and one object of the lnventionis to secure the greatest possible degree of purification at a minimumexpenditure of heat.

A further object is to produce an apparatus which is automatic, orsubstantially so, in its action, and simple, durable, and inexpensive tomanufacture.

With the above and other ob ects in new the invention may be said toconsist in the construction, combination, and arrangement of partshereinafter described, and specifically pointed out in the claims, andin order that said invention may be fully understood, reference will nowbe made to the accompanying drawing, in which:

Figure 1 is a cross sectional View of a steam boiler with the preferredform of my apparatus applied thereto. F g. 2 18 21 plan view of asettlingvessel forming an important feature of the invention, the lid ofsaid vessel being removed. Fig. 3 1s a side elevation of a series ofsettling-vessels communicating with a common outlet pipe. Fig. 4 is adetail side elevat on of one of the settling-vessels and 1ts lid, thelatter about to be placed upon the former. F 1g. 0 is a plan View of oneof the settling-vessels.

A designates a tubular boiler within which are suspended a plurahty ofsettlingvessels a a, by means of spiders Z) 6, secured to the lower endsof eduction pipes ,9 s. The eduction pipes s s are arrangedinoppositely-disposed pairs and communicate with a common outlet pipe .9,which extends through a bushing '10 secured to the top of the boiler.

The outlet pipe s has a union 2?, and a valve 0, which latter controlsthe flow of water through said outlet pipe.

The discharge end of the outlet pipe 8 communicates with the dome of asediment tank B, of any ordinary or preferred type capable ofefficiently separating impurities discharged therein wlth the Water fromSpecification of Letters Patent.

pipe 8. The sediment tank B is provided at its conical bottom portionwith a drain pipe C having a valve E which is opened whenever it becomesnecessary to relieve the tank of all or part of the impurities collectedtherein.

A return pipe 7 leading from the dome of the sediment tank B to thebottom of the boiler A, is provided to carry the purified water fromsaid'tank back into the boiler. The return pipe 1" is provided with avalve (Z to control the flow of waterv therethrough.

The settling vessels a may be made in various sizes and shapes, theimportant point being to have the central points of the bottom portionsdepressed to concentrate the impurities in the water at the mouths ofthe eduction pipes s, so that said impurities will readily enter saidpipes. In the drawing I have shown the settling vessels in two differentforms, that disclosed by Fig. 1, being V-shaped in cross-section, andthe one disclosed by the remaining figures, being substantiallysemispherical. The upper margins of the settling-vessels haveperforations or apertures f, and their upper open ends are closed bylids g, each preferably, made in two pieces, so that it can be removedfrom around the eduction pipe which it embraces when in position on itsrespective settling-vessel. When desired the lid 9 may be perforated asshown on Fig. 5, instead of the bottom of the set-- tling-vessel.

In practice, the circulation of the water in the boiler tends to carryall impurities in suspension even after such impurities becomedisassociated from the water through the application of heat to theboiler, and it is necessary to bring the water to a quiescent state inorder that the impurities may be precipitated through the force ofgravity. This quiescent state of the water is accomplished as it entersthe apertures 7" and flows slowly through the settling-vessels a, whichprotects the water therein from agitation by the outside currents.Consequently the impurities being heavier than the water sink to thebottom of the vessels and become concentrated at the mouths of theeduction pipes s 8, through which they flow to the outlet pipe 8 with acertain proportion of the water, and are collected in the sediment tankB, the purified water then returning to the boiler A through the pipe 7.The foregoing action is automatic and continuous, but when only the mostsimple type of apparatus is desired, the tank B and its pipe connectionswith the boiler are dispensed with and the sediment is collected in thesettling-vessels a,

surface of the water, and consequently they should not be confused withthe usual skimmers which are capable of removing only the lightimpurities which float upon the By' submerging the settling-vessels a,as shown and described, they collect not only the light impurities, butalso heavy particles of scale and other foreign matter which ordinaryskimmer-s would not reach.

'Ihe invention is equally adaptable to stationary boilers, steamtractors, and locomotives.

Having thus described my invention, What I I claim and desire to secureby Letters Patent is: I

1. In a water purifying apparatus of the (lopies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,

character described, a settling-vessel depressed at, its centralbottomportion and having perforated sides, an eduction pipe leading from saidsettling-Vessel at a point adjacent the depressed bottom, a spiderconnecting the settling-vessel to said eduction pipe, and a removablelid embracing the eduction pipe and resting upon the vessel.

2. In a water purifying apparatus for steam boilers, a settling-vesselhaving a depressed bottom, and a removable perforated lid to close thetopof said settling-vessel.

3. In a water purifying apparatus of the character described, asettlingvessel depressed at its central bottom portion, an eduction pipeleading from said settlingvessel at a point adjacent the depressed bottom, and a spider connecting the settlingvessel to said eduction pipe.

4. In a water purifying apparatus of the character described, a settlingvessel adapted to be submerged and having a bottom portion convergingdownwardly from all directions, and an eduction pipe communicating.

with the lowermost part of said bottom portion, substantially as shownand described.
